Studying the content and distribution of molecular gas (H $_{2}$) provides key insights into how feedback from active galactic nuclei (AGNs) and star formation influences galaxy evolution, since molecular gas is the primary fuel for star formation. Ultra-luminous infrared galaxies (ULIRGs) are ideal candidates to study how AGNs and/or starbursts

The microlensing event Gaia20fnr is a long-duration, non-caustic-crossing binary-lens event located at a high Galactic latitude. Triggered by a photometric rise detected by the Gaia space mission, the event was followed up with observations from multiple ground-based facilities and observed by four space telescopes: Gaia, NEOWISE, Swift, and TESS

The advent of new and more powerful infrared spectrographs has significantly motivated the advancement of the study of atomic and molecular line lists and stellar atmosphere models. While optical abundance determinations rely on extensively validated line lists and modeling frameworks, infrared measurements still face comparatively larger

We present a parametric component separation forecast for the QUIJOTE─MFI2 instrument (10─20 GHz) that assesses its impact on constraining polarised synchrotron emission at 1° full width at half maximum and N side = 64. Using simulated sky maps based on power-law and curved synchrotron spectra, we show that adding QUIJOTE-MFI2 to existing WMAP

We present 100 full-sky quasar spectrophotometric mock catalogs with smooth redshift evolution from z = 0 to z ∼ 4, tailored to analyze the Gaia-unWISE Quasar Catalog (Quaia). In particular, we apply a novel hierarchical nonlocal nonlinear bias scheme (Hicobian) to dark matter fields generated through Augmented Lagrangian Perturbation Theory on the

Extremely metal-poor galaxies (XMPGs), defined as having metallicities below 10% of the solar value, are considered possible local analogs to primordial systems and offer a unique window into early galaxy evolution. This study presents a large-scale search for XMPGs using data from the Dark Energy Spectroscopic Instrument Data Release 1
